Description:
Daemon for encapsulating DNS over HTTPS
dnss is a daemon for encapsulating DNS over HTTPS. . It can act as a DNS-to-HTTPS proxy, using https://dns.google.com as a server or anything implementing the same API. . It can also act as an HTTPS-to-DNS proxy, implementing the same HTTP API; you can use this instead of https://dns.google.com if you want more control over the servers and the final DNS server used (for example if you are in an isolated environment, such as a test lab or a private network).
